The manner of practicing and use oit our improved method of forming guides for molding llasks or patterns is as follows z- In lorniing the guides lor the pattern 1, two of such spools 16 are cut in half and on the dotted line 19 shown in Fig. 8, which will forni t'onr halves or segmental bearing portions 20, such as like the one in Fig. Q, and after the jig l has been applied under said iattern, shown in Figs. $5, 4, and the enlarged portions 12 otl the pins l1 on said Will enter the openings l in the lug portions 2 on said pattern. After this is done the sel'ni-circular bearing portions 20 are each placed in the semi-circular por- 'tions 3 of the openil'igs 3 on the pattern 1 and against the enlarged portions 12 on the pins 11 in said opening, so that any suitable filling material, such as the Babbitt metal 21 can be placed around said bearing portions 20 in the portions 3 of said openings to 'hold said hearing portions in place, and after which the jig 7 and pins care removed to torni the pattern seats or vguides 18 in said portions Q0 t'or the reception of the dowel pins hereinafter described and from the holes 18 in the spools 16. In forming the guides for the flask 4, four of the complete spools 1G like the one shown in Fig. 8 are employed, and these spools have their holes 1S slightly smaller in diameter than such holes for forming they guides 1Sl in the semi-circular bearing portions 20. After the jig 7 has been placed on the llask l, so that the contracted lower ends or portions 13 on the pins 11 carried by said j g are Within the holes C in the llange 5 ol said flask, each ol' the spools v16 are placed in said holes and around. said pin portions, and then a suitable lilling material, such as the Babbitt metal 23 can be placed in the spaces lornied'around said spools by said spools and holes-to hold said spools in place, and after this lis done the jig and pins are removed to form the flask guides or seats 18 for the dowel pins hereinafter described.

The dowel pins are shown at 24 and they are each provided With an upper enlarged .pointed end portion and a lower contracted portion 26 thereon. These dowel pins 24 are adapted to tit by their contracted portions' within the guides or seats 18 in the spools 16 of the llask l and are held in place therein by an edge or key 27 passing through a hole 28 in such portions 26 and bearing against the flange 5 of said flask. lVhen the doWel pins 241 are thus in position on the flask d, the pattern 1 can be lowered in the usual manner down onto the said flask, and in such lowering the guides or seats 18 in the bearing portions 20 on said pattern will engage With the enlarged portion 25 on said pins to guide said pattern to place on said flask, as Well as forming such an enlargement-during the raising ot' said pattern from said flask in the usual It will thus be seen that our improved method oli :forming guides in patterns or flasks will enable the formation of guides for the doWelpins in a true and correct line with each other by a single jig, so that When said pins are thus held by the flask the pattern will be guided to its proper position on said l'lask and be precisely matched therewith to form a mold which will enable an even thickness of metal to be had when the article is cast from such mold.

It will be evident that our improved. method of forming guides in patterns or flasks can be applied orn'latching any 'flask or pattern, flasks and llas-ks, or patternsland patterns together, and its use Will overcome the improper alinement and enlarging of the ordinary holes in these mold parts throughcasting and wear, while the method will also permit ot the easy and rapid renewal of the spools for the bearing portions or guides for the pins and thereby prolong the life of the nlold parts carrying the guiding means.

Various modifications and changes lin the design, arrangement and. construction of the devices foi-.practicing our improved method of formingl guides in patterns pr llasks may be resorted to Without departing from the .spirit of the invention or sacrificing any of its advantages.

What We claim as our invention, and desire to secure by Letters Patent, is-

l. 7lhe method herein described ot form- I in the molding appliance, in temporarily.

applying a jig having shouldered seat forming pins to said appliance to determine the position of said guide seats relative to the mold to be Jftnfined, and then securing bearing members in said openings and around said pins to form said seats.

In testimony whereof, We, the said JAMES- H. Danvnn and l/VILLIAM H. Loss, have hereunto set our hands.
